Cuttlefish

Cuttlefish, often mistaken for squid, is a marine mollusk packed with lean protein and essential minerals. While technically a cephalopod, it acts as a 'natural supplement' for vital nutrients like Iron, Zinc, and Selenium. It is prized for its internal shell, the 'cuttlebone,' which is over 90% calcium carbonate. When consumed, it offers a unique profile of amino acids and trace elements that support bone health, thyroid function, and antioxidant defense. Think of it as ocean-raised nutrition that supports your body's structural and metabolic needs.

Health Benefits & Sources

Why You Need It

  • Mineral Density: Exceptionally high in Iron, Zinc, and Selenium.
  • Lean Protein: Provides all essential amino acids for muscle repair.
  • Bone Support: Naturally rich in Calcium and Phosphorus.

Deep Dive

Cuttlefish is a nutritional powerhouse, particularly for those needing a mineral boost. Its iron content helps combat fatigue and supports healthy blood cells, while zinc is crucial for immune function and skin health. Unlike many land-based meats, cuttlefish offers a unique mineral profile derived from the seawater it lives in. The protein is highly bioavailable, meaning your body absorbs it efficiently. Additionally, the compound Sepia (often extracted from the cuttlebone) has a history in traditional medicine for its potential anti-inflammatory and blood-clotting properties, though culinary consumption focuses on the meat.

Natural Food Sources

Cuttlefish is the source itself. However, to maximize absorption of the minerals it provides (like Iron), pair it with Vitamin C-rich foods.
